l .00M-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 312,520, dated February 17, 1885.

Application filed December 13, 1883. (No model.)

To all whom it may concern.-

Be it known that I, JAMES C. SERGESON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Loom-Shuttles, which improvement is fully set forth in the following specification and accompanying drawings,in which- Figure 1 is a side elevation of a shuttle embodying my invention. Fig. 2 is a view:of a portion thereof enlarged. Fig. 3 is a top or plan view of a portion thereof enlarged and partly broken away. Fig. 4 is a transverse section in line x m, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in a shuttle provided with improved means whereby tangles, snarls, and knots in yarn or thread are prevented from passing from the shuttle, as hereinafter fully set forth.

Referring to the drawings, A represents a shuttle, which, excepting the feature ofmy invention, is of well-known form and construction.

B represents the eye through which the yarn from the bobbin or cop is passed out from the shuttle, the same having an open slot, 0, which is formed in the direction of the length of the eye on the side toward the bobbin or cop, and extends from the outer end inwardly a portion of the length of the eye, as most clearly shown in Figs. 3 and 4.

D represents a plate which is secured to the side of the shuttle adjacent to the outer end of the eye B, and has an open slot, E, which extends radially and vertically. The portion of the shuttle-body between the plate and eye is cut away, forming a throat, F, for the passage of the yarn from the eye B to or toward the center of the plate D through the slot E.

It will be seen that when the shuttle is in operation the yarn leaves the bobbin or cop, and then enters the eye B and passes through the slot 0, throat F, and slot E of the plate D, and thus to the loom. The slot 0 permits the ready passage of the yarn from the eye B to the throat F; but should the yarn become snarled, twisted, or tangled, said slot 0 being only a little wider than the greatest thickness of the yarn, its walls act as a check to the twist ortangle and straighten out the same, so that the yarn is passed to the loom in proper condition. Should the. yarn be knotted, or become knotted as it enters the eye B, the knot is stopped by the walls of the slot 0, and unless the same is undone by the draft on the yarn it is held by said walls, thus causing the breakage of the yarn, whereby attention is directed to the cause of breakage, the remedy being the removal of the knot.

When in operation, the yarn deflected by the throat F' passes through the slot E of the plate D in the direction of the line of draft. During the movement of the shuttle the draft draws the yarn against the walls of the slot. If the thread should, by breaking or otherwise, be released from the slot E, it will readily be drawn by the draft, the severed ends having been reunited by tying or otherwise, into the slot 0, pressing against the inner end thereof. It will also be drawn against the curved portion of the plate D, the shorter line of draft being in the direction of the mouth of the slot E, until it falls into the slot E of the said plate, when, being straightened by the draft, it is readily retained in the slot, the mouth of which is in the line of draft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A shuttle formed with the narrow throat F, and provided with a slotted eye and a slotted guide-plate, substantially as and for the purpose set forth.

2. A shuttle having a slotted eye; a narrow throat, F, and a vertically-slotted guide-plate, D, substantially as and for the purpose set forth.

3. A shuttle having a slotted eye,a narrow throat, F, and a slotted guide-plate, D, said throat leading from the slot in said eye to the slot in said plate, substantially as and for the purpose set forth. a
